Okay, he's my situation and what I did:

My Heater/Defroster sucks...

I've been fooling around with my car because my heater and defroster wasn't working properly.  I replaced the old heater valve with a new one, it's working properly.  I then replaced the thermostat in the water-housing.  Turns out there was no thermostat there.  Glad I put that in.  I even went as far as to get me a new control unit since one of the little tubes that the vacuum line connected to broke off...  So I should be good to go - but I'm wrong.

I get heat, and I think my defroster is working, but for some reason, all of it seems to be going to the bottom of my ducts.  I barely get any coming from the middle vents and top vents.  Now, in order for my Defroster to actually work, I need it coming out of my top vents.  I can't figure out what the problem is.  Is there some sort of door that isn't opening?  I hear a sound sometimes (not all the times) when I move the switch from heat to defrost... I'm plain out lost on what to do...

I suspect you are right probably a door or solinoid is not owrking , so you would have to drop the heater box & go through it

So do you think it is the Heater-Defroster Door Crank Arm that isn't working properly?  (See attached Image)

I'm not sure, but that is vacuum operated right?  It plugins into a round silver thing?  I want to be sure what I am going to have to do before I tear out the ducts :)

That's not the right diagram.. I'll try to search on web
Venezuelan RT 74 400 4bbl, 727, 8.75 3.23 open. Now stroked with 440 crank and 3.55 SG. Here is the History and how is actually: http://www.dodgecharger.com/forum/index.php/topic,7603.0/all.html

I might have it, I have a CD Manual for 73 Models, including Charger.  I just need to know which model car is similiar to Charger in terms of the heating system.  I thought it would be the Cornet, which is the above diagram.

Doing some more tinkering around with it today, its either one of two things:  Bad Actuator Valve, or the vacuum hoses are connected wrong.  Does a hose diagram exist to see what I did wrong?  I probably hooked them on wrong when I took my dash frame out.
